Tom Lane 3d40d5e70e Do not allow Unique nodes to be scanned backwards. The code claimed that it ... would work, but in fact it didn't return the same rows when moving backwards as when moving forwards. This would have no visible effect in a DISTINCT query (at least assuming the column datatypes use a strong definition of equality), but it gave entirely wrong answers for DISTINCT ON queries.		2008-08-05 21:28:29 +00:00
